Question

d)
If p(x) = 5x^2 - x, then p(2) + p(-2) is equal to
a) 0
b) 38
c) 40
d) 44​

Answer 1

Answer:

c) 40 is the answer

p(x) = 5x^2 - x

p(2) = 5(2 )^2 - 2

p(2) = 5(4) - 2

p(2) = 20 - 2

p(2) = 18

p(-2) = 5(-2)^2 - (-2)

p(-2) = 5 (4) + 2

p(-2) = 20 + 2

p( -2)= 22

p(2) + p( -2) = 18 + 22

p(2) + p( -2) = 40

c) 40 is the answer
